JSON-LD Schema Markup: A Beginner's Guide

Schema markup is a vocabulary that describes your content to machines. Add it and search engines can display your pages as rich results — with stars, FAQs, breadcrumbs and more.

What JSON-LD looks like

json
{
  "@context": "https://schema.org",
  "@type": "FAQPage",
  "mainEntity": [{
    "@type": "Question",
    "name": "What is schema markup?",
    "acceptedAnswer": {
      "@type": "Answer",
      "text": "Structured data that describes your page to search engines."
    }
  }]
}
